[v1,0/4] x86/microcode: Improve documentation and code

Message

Eslam Elnikety Jan. 22, 2020, 10:30 p.m. UTC

This patch series introduces improvements to the existing documentation
and code of x86/microcode. Patches 1 and 2 improve the documentation and
parsing for `ucode=`. Patches 3 and 4 introduce nits/improvements to the
microcode early loading code.

Some (variant of the) patches have been sent earlier under "Support builtin CPU
microcode" as those patches were motivated by discussions following the initial
submission of the builtin microcode. On a second thought, such improvements
should have gone independently. So here it goes. (Those improvements will be
dropped from the builtin microcode series as I submit its v3).

Changes since submitted under [v2] x86/microcode: Support builtin CPU microcode
- Patch 1: New / explicitly document the current behaviour of ucode=scan with EFI
- Patch 2: Fix index data type, drop unwelcomed function rename
- Patch 3 and 4: Added Acked-by, otherwise as before

Eslam Elnikety (4):
  x86/microcode: Improve documentation for ucode=
  x86/microcode: Improve parsing for ucode=
  x86/microcode: avoid unnecessary xmalloc/memcpy of ucode data
  x86/microcode: use const qualifier for microcode buffer
